OctoTouchController is a dedicated touch screen controller for Octoprint supporting older Android phones / tablets (Android 4.X; device specs: Android 4.x or above, 4inch screen with a minimum resolution of 680x340). Reclaim those old Phones / Tablets that are sitting around that DO NOT have access to the Google store anymore!

This is not a replacement for Octoprint but a way to add a touch screen to your printer using old hardware.

Add a dedicated touch screen to your 3D printer!

Supported Octoprint Plugins include:

Note: If you have a version older than 2.x installed on your device, you will need to uninstall that first before being able to install v2.x or higher. A direct update is not possible, and a change of signing keys has been made to prevent it.

Note: This version is not fully FOSS. It contains some non-libre components to support modern SSL on older devices (Android 4.x). If your device runs Android 5.x or newer, please use/switch over to the new FOSS app instead.

Anti-Features:

NonFreeComp (the application includes non-free components):
⇒ The app contains libraries of Google Mobile Services.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).

Android Support v4 (Development Framework)
The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see Understanding the Android Support Library.
AndroidX Activity (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
Android Jetpack Annotations (Utility)
library that contains the annotations for Android Jetpack.
Arch (Utility)
helper for other arch dependencies, including JUnit test rules that can be used with LiveData.
Android Support Library collections (Utility)
standalone efficient collections.
Androidx Core (Utility)
a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.
Android Support Library Custom View (UI Component)
a module to implement custom views. Part of the Android Support Library.
AndroidX Fragment (UI Component)
AndroidX library to encapsulate part of the user interface or behavior into reusable components.
Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
Loader (Utility)
library to load data for your UI that survives configuration changes.
Android Activity Saved State (Utility)

B4J core libraries.
Google Mobile Services© (Development Framework)
Google Mobile Services in terms of the Android library refers to Google Play Services, a proprietary background service and API package for Android devices which is not part of the Android Open Source Project (AOSP). The library does not contain those services (i.e. it usually requires the Google Framework, often referred to as „GApps“, being installed on the device), but allows an app to communicate with them. Be aware this usually goes along with transferring at least parts of your personal data to the Google network.
OkHttp (Utility)
OkHttp is an HTTP+HTTP/2 client for Android and Java applications.
Float Labeled EditText (UI Component)
simple implementation of a Float Labeled EditText: An Android ViewGroup which uses a child EditText and puts the hint on top of the EditText when it is populated with text.
Autobahn Java (Utility)
a lient library providing WAMP on Java 8 (Netty) and Android, plus (secure) WebSocket for Android.
OkHttp okio Framework (Utility)
